HP OfficeJet 7310 Broken Cartridge Spring Arm Holder

I have not used this printer much for a year and barely before that. Just moved my office home, and wanted to make use of it upstairs. Had to go buy a new black cartridge because it said it was out. I did that.

Now, I keep getting error messages to take out the black print cartridge. I finally got down and looked, and the little spring that is held in by a tiny piece of grey plastic is loose and the plastic spring holder is gone. I've done a search on google, and it turns out this is common and breaks easily. I wonder how I find a replacement part?? I appreciate any help on this, as my larger fax/copier/scanner now needs a new color toner, which will take a week to get here!

Re: HP OfficeJet 7310 Broken Cartridge Spring Arm Holder

HP was replacing Officejet 7xxx series printers free of cost for this particular issue. Unfortunately, this was only until 31st december 2008. You can call HP tech support and ask them what options are available for you at the moment. I'm pretty sure you'll have to pay for the service.

Re: HP OfficeJet 7310 Broken Cartridge Spring Arm Holder

I have encountered this problem with my Photosmart 7150. The plastic piece which secures the spring for the black cartridge holder is broken. The part number listed for the "Print Cartridge Protector", which I suspect is the cartridge holder with the attached door, is #5064-4554.

Questions:

1. Can the problem be fixed without buying a part?

2. If not, can I just buy the door which contains the broken latch? What is the part number?
